Nothing really serious with the fix in OpenSSL that concerns Apache, just one rated moderate and one low.

Constructed ASN.1 types with a recursive definition could exceed the stack (CVE-2018-0739)==========================================================================================

Severity: Moderate

Constructed ASN.1 types with a recursive definition (such as can be found inPKCS7) could eventually exceed the stack given malicious input withexcessive recursion. This could result in a Denial Of Service attack. There areno such structures used within SSL/TLS that come from untrusted sources so thisis considered safe.

This issue has been reported in a previous OpenSSL security advisory and a fixwas provided for OpenSSL 1.0.2. Due to the low severity no fix was released atthat time for OpenSSL 1.1.0. The fix is now available in OpenSSL 1.1.0h.

There is an overflow bug in the AVX2 Montgomery multiplication procedureused in exponentiation with 1024-bit moduli. No EC algorithms are affected.Analysis suggests that attacks against RSA and DSA as a result of this defectwould be very difficult to perform and are not believed likely. Attacksagainst DH1024 are considered just feasible, because most of the worknecessary to deduce information about a private key may be performed offline.The amount of resources required for such an attack would be significant.However, for an attack on TLS to be meaningful, the server would have to sharethe DH1024 private key among multiple clients, which is no longer an optionsince CVE-2016-0701.

This only affects processors that support the AVX2 but not ADX extensionslike Intel Haswell (4th generation).
